Are calls to the sessionless API possible without an active session from a desktop app  ?

Typically, desktop apps have to supply a session key or otherwise cannot use API methods that don't require a session. See Category:Sessionless_API for the list of calls that don't require a session. Pete (563683308 11:23, 7 August 2009 (PDT))

Are sessions bound to a user ? Does 'anonymous' session exists that would act on the behalf of the app ?

Sessions are bound to a user, yes. However, you can prompt a user for the offline_access extended permission so you can make API calls on behalf of the user without the user being logged in. What are you looking to do on your app's behalf? Pete (563683308 11:25, 10 August 2009 (PDT))
